network structure and we examine equilibrium selection. Specifically, actions are either strategic substitutes or strategic … complements, and participants have either complete or incomplete information about the structure of a random network. Since … networks, such as connectivity, clustering, and the degree of the players, help to predict informed behavior in the lab. People …

This paper reports results from a laboratory experiment on network formation among heterogeneous agents. The … experimental design extends the Bala-Goyal (2000) model of network formation with decay and two-way flow of benefits by allowing … private information. In all treatments, the (efficient) equilibrium network has a "star" structure. With homogeneous agents …

When workers send applications to vacancies they create a network. Frictions arise because workers typically do not … friction affects network formation, while the second coordination friction affects network clearing. We show that those … frictions and the wage mechanism are in general not independent. The wage mechanism determines both the distribution of networks …

We consider a model where each individual (or ethnic minority) is embedded in a network of relation-ships and decides … assimilation norms may emerge in steady state depending on the structure of the network. We then consider the role of cultural and …

We study the impact of research collaborations in coauthorship networks on research output and how optimal funding can … maximize it. Through the links in the collaboration network, researchers create spillovers not only to their direct coauthors … possibly overlapping projects. We bring our model to the data by analyzing the coauthorship network of economists registered in …

network formation. While the physics/applied mathematics approach is capable of reproducing most observed networks, it does …We survey the literature on social networks by putting together the economics, sociological and physics … not explain why they emerge. On the contrary, the economics approach is very precise in explaining why networks emerge but …
